Calculate how much mulch to order in cubic yards for bulk delivery, or how many 2 cu ft bags to buy at a garden center.
How it works
- Enter the length and width of the garden bed.
- Define how many inches deep you want the mulch to be.
- Read the output for total cubic yards and standard 2-cu-ft bag counts.
Frequently asked questions
How deep should mulch be?
2-4 inches is ideal. Shallower fails to suppress weeds; deeper than 4 inches can prevent water from reaching roots.
Bulk vs bags — which is cheaper?
Bulk is far cheaper per cubic yard for quantities over 2 yards. Bags are convenient only for small areas.
Should mulch touch plant stems?
No — keep mulch 2-3 inches away from stems and tree trunks to prevent rot and pest damage.
